Question

A particle is placed at the point **A** of a frictionless track **ABC**. **A** is the top of a step $$1 \, 	ext{m}$$ above the ground, **B** is a point on the curved part of the track $$0.5 \, 	ext{m}$$ above the ground, and **C** is a ledge again $$1 \, 	ext{m}$$ above the ground. The particle is gently pushed towards the right. The speed of the particle when it reaches the point **B** is: (Take **$$g = 10 \, 	ext{m/s}^2$$**)

Accepted Answer
